UNITED STATES PATENT OFFIC JOHN A. \VILLIAMS, OF NEW YORK, N. Y., ASSIGNOR TO THOMAS ADAMS, JR.,

OF SAME PLACE.

SELF-LIGHTING GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 627,632, dated June 27, 1899.

Application filed November 26, 1897. Renewed May 26, 1899. $erial No. 718,427. (No model.)

To all whom it may concern:

Be it known that I, JOHN A. WILLIAMS, a citizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Self -Lighting Gas-Burners, of which the following is a specification.

My present invention relates to automatic gas-lighters, the construction and advantages of which will be hereinafter set forth, reference beinghad to the annexed drawing,in: which the burner and lighter are shown in perspective. a

The object of the invention is to provide means for automatically lighting the gas when it is turned on and by the heat generated by the flame to withdraw the igniting substance or body out of the flame.

The present case is designed to be an embodiment of my broad invention disclosed in an application, Serial No. 659,872, filed by me on the 26th day of October, 1897. 2

Referring to the drawing, A designates a burner, which may be of any of the ordinary or usual types, to which, at its upper end, is attached or connected an outstanding lug or projection B. To this lug is attached one end of a thermostatic coil 0, which, as shown, extendsdownwardly and surrounds the burner at a slight distance therefrom. I The coil may be composed of any two metals which have dift'erentcoefficients of expansion, the layers a andb being, as shown, superimposed one above the other, so that the coil will expand and contract in the direction of the length of the burner. Connected to the lower end of the coil is an arm or rod D, which extends upwardly to a point above the burnertip and in line with the opening thereof. At its upper end it is provided with a basket E, containing a substance capable of condensing or absorbing oxygen and causing the gas to igniteLbycoming into contact therewith. The substance employed may be platinumblack or any other material possessing the property of causing the gas to ignite. So, too,

while I have spoken of a basket as the means for holding the substance, I do not desire to be understood as limiting myself thereto, as other means may be employed to sustain the igniting material. A rod or arm F, similar to rod D, is rigidly connected thereto by a ring G, which passes around outside of the coil. Said arm F also carries at its upper end a basket for holding igniting material.

Secured to the lower end of the burner is a stop II, which serves to limit the downward movement of the coil due to its expansion when heated.

The normal relation of the parts is shownin full lines in the drawing, the flow of gas being shut 0E and the rods and igniting ma= terial elevated.

.When the gas is turned on, it will, as it issues from the tip, come into direct contact with the igniting substance and burn. Immediately this takes place the coils will be gin to separate, due to the action of the heat thereon, as will be well understood, and the rods'or arms D and F will be drawn down into the position indicated in dotted lines, the lower ends of the bars coming into contact with the stop H and the igniting material being withdrawn from the flame. This position of the parts will be maintained as long as the flame continues to burn. 80 soon as the gas is shut off the coil will begin to contract, due to the thermostatic action, and the igniting material will be again elevated into a position ready to ignite the gas when it is again turned on.

Having thus fully described my invention, what I claim is- 1. In combination with a gas -burner; a thermostatic coil surrounding the same and connected thereto at one end, said coil consisting of two metals superimposed one above the other; and a substance capable of igniting the gas by coming into direct contact therewith, carried by the free end of the coil tending upwardly in line with the burner; and a substance capable of igniting the gas by coming into contact therewith, carried by the upper end of-said bar.

3. In combination with a gas-burner; a

thermostatic coil surrounding the same and connected thereto at its upper end; a bar or rod connected to the lower end of the coil extending upwardly in line with the burner; an igniting substance carried by the bar; and a stop to limit the downward movement of the bar.

4. In combination with a gasburner; a thermostatic coil surrounding the same and connected thereto at its upper end; a bar or rod connected to the lower end of the coil; a second rod or bar upon the opposite side of the burner; a connection between said rods; and igniting material carried by the upper ends of the rods.

5. In combination with a gas -burner; a
